To cZZZ whom it may concern: 3

Be it known that I, HERBERT H. HAM, of the borough of Manhattan, city of New York, county and State of New York, have invented 5 certain new and useful Improvements in Ball-Bearing Spindles for Spinning-Frames, of which the following is a specification.

My present invention is an improvement upon spindles now most generally used in re many respects, among them in the fact that in spindles as heretofore made the bolster is bored interiorly and the spindle extends from above downwardly through the bolster and engages with a bolster-case at its lower I 5 end; also, there is no suitable means to .pre-f vent the escape of the lubricant; also, the

spindles now on the market are much more expensive than mine. i I am aware that heretofore the attempt has been made to make spindles with solid bol sters and ball or roller bearings, but so far as I am aware they have never been successful, because, first, of the complexity of their construction; second, the difiiculty'of'maihtaining the lubricant within the moving parts;

third, the impossibility of using a dry lub'ri cant; fourth, the lack of adjustability of the parts, so that lost motion consequent upon wear may be taken up, and, fifth, the insta 3o bility of the parts or chattering of the spin dle after a slight use, consequent upon the lack of adjustable devices, as above stated. Under my present invention the parts are of the simplest form, theyare few in number,

are of such character that they are not likely to wear rapidly, the machine is adapted-to use a dry lubricant, provision is made for lubricating the upper set of balls equally with the lower set, adjustable features are present,-

40 whereby the spindle may be made to run silently and smoothly irrespective of the degree of its use, and the parts may be interchangeable, so that the wear or fracture of a single part can be in a moment replaced by a new one.

I have demonstrated that my spindle, not

withstanding the fact that it embodies the ball-bearing principle, can be made and sold commercially far below the cost of the spindles now most largely used.

Referring to the drawings hereof, Figurel illustrates an elevation, partly in vertical section, of the apparatus complete, the spindle being broken off. Fig. 2 illustrates in elevation the cap towhich the spindle is attached or which forms part of it, as preferred. Fig. 3 illustrates a vertical sectional view of the whirl. Fig. 4 illustrates an elevation of the bolster. Fig. 5 illustrates an elevation of the spindle. Fig. 6 illustrates a' detail of the parts adjacent to the lower ball-bearing.

A (see Fig. 4) is the bolster. his solid from end to end. B are threads at or near itslower partfupon which engages the nut 0, whereby the bolster is rigidly fastened in the spinningframes. I

- D is an annular seat tosupport the cone of the lower ball-bearing.

E is an upwardly-projecting stem provided with screw-threads F at its upper end, whereby the upper ball-bearing cone and adj ustingnut are attached and'manipulated.

G is'the cone of the lower ball-bearing. It

is preferably, but not necessarily, made sepa rate from the bolster as a highly-finished casehardened part, which'issupported upon the seat D of the bolsteryas shown.

I G (see Fig. 3) is the whirl. It is bored ecu trally, as at H, for thereception of the stem E of the bolster and at its lower part has a recess I, provided with annular grooves J J to aid in holding the lubricant. At its upper end there is another recessK, provided with a recess K at its lower part. a

L (see Fig. 1) is the conefor' the upper ballbearing, which is bored and threaded centrally to engage with the screw-threads F, and it is provided with a lock-nut'M,whereby it may I be exactly adjusted; The side of the stem F is cut away, as seen at F, so as to square that side, and a washer M, having a hole in it of the same shape as the cross-section of the stem at the cut-away or squared part, is placed on the stem between the cone L and the nut M, so that the parts referred to will act as a lock for the cone when once adjusted.

.The upper part of the whirl is preferably, but not necessarily, tapered exteriorly, as shown at N. O is a cap, tapered interiorly to conform to the exterior taper of the part N of the whirl and is adapted to make a snug fit with it and be rigidly clamped thereto by set 1 screws P P. This is my preferred construc tion, because where there is a slight taper given to these parts a more accurate joint between the two can be made than where they are parallel-sided, and I find in practice that when this construction is employedeconom-yin manufacture results. Obviously,however; the parts can be made of such shape as preferred and connected together in any suitable manne 4 .e V j l Q is the spindle. It is made as sho best in Fig. 5 and enters the opening R in the up '2 a I r 654,892

base of the lower ball-bearing cone G, so that there will be no escapeof the lubricant at this point. The lubricant which I prefer to use is I asuitable preparation of plumbago or equivalent material; and it quickly closes such slight opening as there may be at this joint, so that there isno escapeof it. 'In order, however, to preclude all possibility of the escape of lubricantfl sometimes make the lower hearing as shown in Fight, in which the parts are the sameas above indicated, excepting that the cone is shown as made solid with the bolster and the lower edge T of the whirl Gisrabbeted and the coacting part of the bolster is likewise rabbeted, so that this steppedco'nstruction will with certainty preclude the es-,'

cape of thelubricantwhatever it may be.

' U Urarethe balls. 7 The assembling-and operation of the parts are obvious and do not require specific description. I call especial attention ,to the fact, however, that all of the parts are of the simplest possible construction, that the-single' adjustment of the cone for the upper ballbearing by means of the set-nut M takes up all lost motionboth laterally and vertically, and by this simple device all chattering of the spindle can be prevented; also, that by reason of'the channels J,'J, and K the lubricant will be held adjacent to the balls at all times and that it cannot escape from these bearings, that the spindle is detachable from the whirl by simply loosening the set-screws P, thatthe spindle as a whole is so constructed that its parts whenassembled are inseparably connected together, so that it may be made,

assembled, and adjusted at the shop of the manufacturer and sold in a complete conditionjready for immediate use to the trade t also,-that a single part-to wit,the upper cone, with its set-nut M provides means whereby the-entire apparatus maybe quickly and easily adjusted and lost motion taken up, and, --lastly, that a dry lubricant may be used without danger of its escape to injure the goods being woven.
